Application filed March 8, 19231 Serial No. 623,706.

To all whom it may concern:

Be it known that I, ANDREW MAXWELL, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented new and useful Improvements in Dustguards, of which the following is a specification.

The device which is the subject matter of the present application for patent is a dust guard designed for use in connection with motor vehicles, railway cars, etc., for preventing or minimizing the raising of dust when the car is traveling over dusty roads, and the object of the invention is to provide a dust guard of this kind embodying certain novel and improved features of construction to be described in detail hereinafter, and also to so mount the guard that it will readily clear obstructions and pass over the same without being damaged.

With the objects stated in view, the invention consists in a combination and arrangement of parts to be hereinafter described and claimed, and in order that the same may be better understood, reference is had to the accompanying drawings, where- 1n- Figure 1 is a plan view of the device;

Fig. 2 is a cross-section on the line 2-2 of Fig. 1;

Fig. 3 is a longitudinal section on the line 3-3 of Fig. 1; s

Fig. 4 is an end elevation of the device viewed from the rear;

Fig. 5 is a cross-section of the device as applied to a railway car, and

Fig. 6 is a perspective view of a support for the device when used in this relation.

In the drawings, so much only of a motor vehicle is shown as will make clear the connection of the invention therewith. The numeral 10 denotes the rear axle, and the numeral 11 denotes the differential housing. The housing which extends lengthwise beneath the car body and encloses the drive shaft is shown at 12, and at 13 is shown a fragment of the car body.

The dust guard consists of two members 14 made of sheet metal or other suitable material, and positioned lengthwise beneath the car body 13 on opposite sides of the longitudinal center line thereof. The dust guard members are curved transversely, with their concave sides presented outwardly or in the direction of the respective sides of the car. The overhanging portion of the yield rearwardly in the direction of their length if their front ends should meet an obstruction, and to prevent wear of or damage to their forward ends, said ends are fitted with a wear shoe 15 which is mounted be tween said ends. The dust guard members therefore readily pass over obstructions without danger of being damaged. The suspension means comprise the following parts:

To the housing 12 is secured a pair of clamps 16 each carrying a depending bracket arm 17, to the lower end of which latter is pivoted, as shown at 18, the'upper ends of a pair of links 19. To the inner faces of the members 14 are secured reinforcing strips 20 to which the lower ends of the links are pivoted, as shown at 21. A curved brace bar 22, connects the rear ends of the strips 20 and extends transversely therebetween. Intermediate their ends, the strips 20 are bridged by a transverse web 23 which latter, with the bar 22 provide a rigid connection between the members 14 so that they may yield together as hereinbefore described.

and swing as one.

The guards 14 effectually prevent dust from settling on the body, the seats and the running gear of the car, as well as on the occupants. The rising road dust is caught up by the guard members and deflected rearwardly a sufficient distance so that when it issues from the rear ends of the guard members it does not settle on any portion of the car. The device is simple and efficient, and it can be readily applied without changes in the structure of any parts of the car.

If the guards 14 are to be used in connection with a railway car, the supporting frame shown in Fig. 6 will be employed. This frame consists of a pair of longitudinally spaced V-shaped hangers 24 secured in any suitable location beneath the body of the car shown at 25 in Fig. 5. At their upper ends, the branches of the hangers 24 are connected by cross bars 26, and these cross bars, in turn, are connected by a longitudinal bar 27. At the bottom, the hangers 24 are connected by longitudinal bars 28. Intermediate their ends, the bars 27 and 28 have bends towards each other and terminating in two opposite and vertically spaced portions 2.7 and 28, respectively, through which passes a king-bolt 29, said bolt serving to support the guards 14 by passing through the web 23, and said web seatingbetween the parts 27 and 28 The king-bolt 29 provides a pivotal support for the guards 14 so that they may be swung around, and positioned according to the direction in which the car is to travel. For the purpose of holding the guards 14: stationary, the hangers 24; carry chains 30 at their lower ends, and said chains are equipped with hooks 31 at their free ends for attachment to any convenient portion of the car, the chains being somewhat loose to give the guards lateral play when rounding curves.

I claim:

1. A dust guard for road vehicles, eomprising a pair of guard members positioned beneath the vehicle and extending in the direction of the length thereof, and said members having a transverse curvature with their concave sides outwardly presented.

2. A dust guard for road vehicles, comprising a pair of guard members positioned beneath the vehicle and extending in the direction of the length thereof, and said members having a transverse curvature with their concave sides outwardly presented, and a pivotal support for said members to permit a rearward swing thereof in the direction of their length.

3. A dust guard for road vehicles, co1nrising a pair of guard members positioned eneath the vehicle and extending in the direction of the length thereof, and said members having a transverse curvature with their concave sides outwardly presented, a wear shoe fitted to the forward ends of said members, and a pivotal support for said members to permit a rearward swing thereof in the direction of their length.

4:. A dust guard for road vehicles, comprising a pair of guard members positioned beneath the vehicle and extending in the direction of the length thereof, and said members having a rearward divergence, and a transverse curvature with their concave sides outwardly presented.

5. A dust guard for road vehicles comprising a guard positioned beneath the same and shaped to deflect dust rearwardly, and a pivotal support for the guard to permit a rearward swing thereof in the direction of its length.

6. A dust guard for road vehicles comprising a guard positioned beneath the same and shaped to deflect dust rearwardly, a wear shoe fitted to the forward end of the guard, and a pivotal support for the guard to permit a rearward swing thereof in the direction of its length.

7. A dust guard for road vehicles cont prising a guard positioned beneath the same and shaped to deflect dust rearwardly, and depending pivoted links carried by the vehicle and supporting the guard.

8. A dust guard for road vehicles, comprising a pair of guard members positioned beneath the vehicle and extending in the direction of the length thereof, and said members having a transverse curvature with their concave sides outwardly presented, and depending pivoted links carried by the vehicle and supporting the guard members.

In testimony whereof I aflix my signature.

ANDREW MAXWELL.
